SPECEIIGATIQN forming part of Letters Patent No. 704,401, dated July 8,1902.

Application filed March 22, 1898.

T (1.7] whom it may concern: 7

Be it known that I, JULIUS TALUAU, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Improvement inFraming Glass,

&c., of which the following is afull, clear, and

exact description.

In the application for patent for stained- IO glass windows and similarobjects iiled by me on December 16, 1895, Serial No. 572,318, I havesought to cover the manufacture of such objects by the substitution ofan electrodeposited framing for the lead framing there- [5 tofore commonin the manufacture ofsuch objects, and I therein described variousmethods of carrying out my invention. Among other things, there isdescribed in said application a support upon which-the pieces to beunited are arranged in relative position with spaces between them, whichspaces contain a conductor of electricity, so that when the object isplaced in an electrolytic bath under proper conditions the spaces willhe filled with deposited metal which will form a frame for uniting theseveral pieces in a unitaryobject. I have therein described also thecementing of the pieces to the support in order to hold such pieces inplace during the period of electrodeposition and to permit the removalof the support or foundation.

At the date of the aforesaid application it was old and well known inthe art to provide a stained-glass window or other composite article ofsimilar character with a frame, so as to enable the use or setting ofthe objects.

This present case relates to certain forms of the broad invention commonto the case referred to and tothis and is designed to cover o themspecifically.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure 1 showspieces of glass arranged upon a support ready for theelectrodepositing-bath. Fig. 2 is a cross-section'on an enlarged andexaggerated scale. Fig. 3 is a cross-section, also on an enlarged andexaggerated scale, showing the object after the completion of theelectrodepositing process. Fig. 4 is a cross-section, also on anenlarged and exag- Serial No. 674,813. (No model.)

gerated scale, of one of the finished objects. Fig.5 is a plan view andcross-section showing the finished object framed. Fig.'6'is aperspective view of one form of electrolytic apparatus that may beemployed in carrying out my invention.

The foundation, backing, or support a may be of lead-foil or sheet-leador other metal or metallized body; but Whether such support be itself aconductor or be capable of receiving a conductor of electricity itshould be or be made to be of sufficient rigidity to support the piecesof glass or other material to be united in a unitary design. The piecesof glass or other material I) are appropriately arranged upon thissupport to form the desired object, and spaces 0 are left between theiradjacent edges. The pieces I) may be cemented to the support by-theinterposition of suitable 7o adhesive material (1, and my invention isnot limited to the kind of cement, I having used wax,amongothersubstances, for this purpose. If the support itself be not a conductor,then the pieces of glass are assembled on such support, as before, andthen the support is provided in the spaces between the pieces with themetallic surface, as at e, that will serve as a conductor. For thispurpose any suitable metallic powder may be used. Whatever the nature ofthe support and conductor the object to be framed after being preparedas described is subjected to the ac tion of an electrolytic bath-such,for example, as that shown inFig. 6,-whereinfis the vessel; gand 7t, theanode and cathode, respectively; dabattery or other source ofelectricity, and 7c the proper solution or electrolyte. When the spaceshave been filled with the electrodeposited metal, as at Z, Figs. 3 0 and4, the object may be removed from the bath, and it is then ready forreceiving its permanent casing'or frame, such as m,Fig. 5, the supportbeing removed or'retained according to whether or n'ot'a transparency is9'5 desired. The electrodeposited frame may be formed also around theperimeter of the object, as indicated at a; but that feature of theinvention is claimed in the application hereinbefore mentioned.

As already indicated, 1 seek herein to claim certain specific forms ofthe invention which 1. The method of uniting pieces of glass or othermaterial, which consists in arranging such pieces on a support to holdthem in rela tive position with spaces between them, then providing anelectric conductor on such support in proximity to such spaces, thenexposing in an electrolytic bath and electrodepositing on such conductorand within such spaces until the spaces are entirely filled withdeposited metal, so as to form an electrodeposited holding-frametherefor.

2. The method of electroglazing glass and other substances, consistingin providing a support upon which the several pieces are placed in suchmanner as to have their adjacent edges slightly separated, somecementitious or adhesive material being interposed between the supportand the pieces, the spaces between the pieces being provided with anelectric conductor, then inserting the object into an electrolytic bathand depositing material upon the electric conductors between the severalpieces, and then removing the support.

8. The method of forming a series of pieces of glass or other substancesinto a body, consisting in placing the several pieces upon a support insuch manner that their adjacent edges will be slightly separated, aquantity of cementitious or adhesive material being interposed betweenthe pieces and the support, then applying electrically-conductedmaterial in the-spaces between the several pieces, then immersing thebody in an electrolytic bath and depositing metal between the parts tobe connected, and thereby connecting the pieces to adapt them to receivea surrounding frame, the support being removed or retained as desired.

In testimony whereof I have hereunto set my hand this 18th day of March,1898.
